3 | {\bf Note:} constraints are now deprecated and you should use \helpref{sizers}{sizeroverview} instead. |

5 | Objects of this class can be associated with a window to define its |
6 | layout constraints, with respect to siblings or its parent. | |
7 | ||
8 | The class consists of the following eight constraints of class wxIndividualLayoutConstraint, | |
9 | some or all of which should be accessed directly to set the appropriate | |
10 | constraints. | |
11 | ||
12 | \begin{itemize}\itemsep=0pt | |
13 | \item {\bf left:} represents the left hand edge of the window | |
14 | \item {\bf right:} represents the right hand edge of the window | |
15 | \item {\bf top:} represents the top edge of the window | |
16 | \item {\bf bottom:} represents the bottom edge of the window | |
17 | \item {\bf width:} represents the width of the window | |
18 | \item {\bf height:} represents the height of the window | |
19 | \item {\bf centreX:} represents the horizontal centre point of the window | |
20 | \item {\bf centreY:} represents the vertical centre point of the window | |
21 | \end{itemize} | |
22 | ||
23 | Most constraints are initially set to have the relationship wxUnconstrained, | |
24 | which means that their values should be calculated by looking at known constraints. | |
25 | The exceptions are {\it width} and {\it height}, which are set to wxAsIs to | |
26 | ensure that if the user does not specify a constraint, the existing | |
27 | width and height will be used, to be compatible with panel items which often | |
28 | have take a default size. If the constraint is wxAsIs, the dimension will | |
29 | not be changed. | |
